Product Description:

1. Structure of Check Valve Description


This product is designed and manufactured fully in accordance with API Spec 6A wellhead and Christmas tree equipment standards,and can thus be used interchangeably with the products manufactured at home and aboard,which tally with API Spec 6A specifications ,or used to form a complete system.


This is a type of check valves which rely on the pressure of working medium to get meal-to-meal sealing between the core and body(seat). The higher the medium pressure,the better the sealing performance. It is always able to withstand the pipeline pressure within the value cavity.


The body of the valve is forged with alloy steel,which has solid mechanical properties and is able to withstand high pressure in safty and reliability.


The bonnet and the body of the valve are connected with blinding bolts. Sealing washers are used to seal up the bonnet and the interior wall, which reduces the space in between to a minimum (designed as 0),thereby considerably minimizes the erosion of the bolts and the bolt holes,caused by erosive  media,and also decreases the load taken by the bolts.


2. Main Features of Check Valve


1) Fitted  with a valve-opening indicator
2) Designed with the relief valve
3) Designed with the plane thrust bearing structure
4) Designed with the meal-to-meal sealing structure
5) Fitting with the valve stem sealed by using some special material made lip-shaped packing
6) Made of high wear-resising& corrosion-resising materials, both the valve core and bean are durable
7) Designed and manufactured strictly in accordance with API Spec 6A ,ANSI and NACE MR-0175 standards.

Q:valve oil mass order?
Refills? okorder.com they are horrible!
Q:what exactly causes a valve to stretch?
It is probably a combination of the above answers, plus heat. I would think heat is the primary cause of the stretch. As you know metal expands, when it gets hot. It will also shrink when cooled. There is probably a point where they will only shrink back to a certain spot and still remain in the stretched position.
Q:Valve cover gasket leak?
I have see one time that a car had blown valve cover gasket. It leak very well and Touch on Exhaust Madifold. It cause fire. Engine is High milages. Engine make blow by through piston and cylinder. Bypass gas cause Press gaskets or seals to make oil leaks. Other thing is loose vaccum for brakes. It make hard to press brakes. Like air leak. OR Rubber valve cover gasket getting dry up, and start brittles. Its ten years old, So go and replace valve cover. If you know how, That will be great. Do it asap Than Sorry.
Q:natural gas furnace valve not opening?
I realize this is probably a dumb question, but it has to be asked, just so everyone else won't have to wonder. Are you dead sure you put the valve on in the right direction? I'm not a certified furnace installer or repair person, so I don't actually know if it's even possible to put a valve on backwards, so, the question. It certainly sounds like you've done everything that could be done, other than to take the valve off and try getting it to open while it's off. If it's opening, it should do it on a bench, with 24 volts going to it. You may have to take the transformer with it to be sure, and actually look up in the holes to see if you can spot the flap opening up for the gas to flow. You haven't mentioned a pilot at all, so I have to wonder if this is an igniter type system? That would be my methodology of checking the valve and the transformer. If you can get it to open on the bench, then it certainly should open in place.
Q:My air pumps check valve doesn't work?
Or if you can, go to petsmart and get one there. Petco tends to sell sub-par items and livestock. If you have a tank that is bigger than your air pump was intended, then you will have problems. Say you bought a 10 gallon air pump for your 20 gallon tank. The strength of the pump is only able to push air down to counteract the average depth of a 10 gallon tank, against the pressure of only that much water. However if it were in a 20 gallon, it may not be able to counteract the water and the check valve (which shouldn't be causing much of a problem anyways). Make your line shorter and see if that helps. You don't need tons of extra airline tubing coiled around. Cut it down to the length you need, and try again. Remember, check valve should be OUTSIDE of the water, in the direction indicated on the valve (as to which side is in, which side is out), and it should be closer towards the pump itself. The check valve just prevents any water from dripping back into the pump.
Q:What are compensating valves on a Brass instrument?
A compensating valve instrument has valves that send the air through two sets of tubing. For example a double French horn has slides for the F side and the Bb side. In a normal horn the air goes through the F side when you are playing the F side and the Bb side when you are playing that side. In a compensating horn when you play the F side the air goes through both sets of slides. It's a way of making the horn lighter and simpler.
Q:How is a pig hearts valve used to replaced ours?
I have had heart surgery and they ruled out replacing my valve with a pig valve because they only last about 5 years. They replaced mine with a mechanical valve, and so far it's amazing! If they replace your valve I believe they basically cut out the defective one and sew in a new valve, animal or man made. If replaced with a pig valve you must be on anti-rejection medicine, and have it replaced every five years or so. With a mechanical one you have to be on blood thinners, but they assume (last I heard) they should last a minimum of 40 years, probably longer.
Q:Valve job? Cheapest way?
Probably just the valve stem seals need replacing. NOT a entire 'valve job'. The seals help scrape oil off of valve stem to lower the amount of oil weeping into cylinder when engine is running or turned off. As the rubber ages, it cracks and loses its elasticity and doesn't wipe the stem properly. This is a lot cheaper versus a full 3-angle valve job which requires removal of the heads.. Get a second opinion.
Q:what is a imt valve the ecm has detected that the imt valve is stuck open?
Remove it and clean it.
Q:Does a diverter valve make the same basic sound that a blow off valve does?
No. A diverter will typically be installed before any catalytic converter or muffler to allow you to have a free straight flowing exhaust by dumping the exhausted there. it has two out puts and one input. one out goes to stock exhaust one to open exhaust. Noise on demand really. Blow off valves for are for Turbo charged cars and make a whistling noise when they release air pressure when u let off the gass.
